BOOST_DATA_TEST_CASE with fixture support

I'm looking for fixture support in BOOST_DATA_TEST_CASE. I wrote following C++ macros for it, but may be somebody has something better?

#include <boost/test/unit_test.hpp> #include <boost/test/data/test_case.hpp> #define BOOST_FIXTURE_DATA_TEST_CASE_IMPL( arity, test_name, F, dataset, params ) \ struct test_name : public F { \ template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)> \ static void test_method( BOOST_DATA_TEST_CASE_PARAMS( params ) ) \ { \ BOOST_TEST_CHECKPOINT('"' << #test_name << "\" fixture entry."); \ test_name t; \ BOOST_TEST_CHECKPOINT('"' << #test_name << "\" entry."); \ BOOST_TEST_CONTEXT( "" \ BOOST_PP_SEQ_FOR_EACH(BOOST_DATA_TEST_CONTEXT, _, params)) \ t._impl(BOOST_PP_SEQ_ENUM(params)); \ BOOST_TEST_CHECKPOINT('"' << #test_name << "\" exit."); \ } \ private: \ template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)> \ void _impl(BOOST_DATA_TEST_CASE_PARAMS( params )); \ }; \ \ BOOST_AUTO_TU_REGISTRAR( test_name )( \ boost::unit_test::data::ds_detail::make_test_case_gen<test_name>( \ BOOST_STRINGIZE( test_name ), \ __FILE__, __LINE__, \ boost::unit_test::data::make(dataset) ), \ boost::unit_test::decorator::collector::instance() ); \ \ template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)> \ void test_name::_impl( BOOST_DATA_TEST_CASE_PARAMS( params ) ) \ /**/ #define BOOST_AUTO_DATA_TEST_CASE_WITH_PARAMS( test_name, dataset, ... ) \ BOOST_FIXTURE_DATA_TEST_CASE_IMPL( BOOST_PP_VARIADIC_SIZE(__VA_ARGS__), \ test_name, BOOST_AUTO_TEST_CASE_FIXTURE, dataset, \ BOOST_PP_VARIADIC_TO_SEQ(__VA_ARGS__) ) \ /**/ #define BOOST_AUTO_DATA_TEST_CASE_NO_PARAMS( test_name, dataset ) \ BOOST_AUTO_DATA_TEST_CASE_WITH_PARAMS( test_name, dataset, sample ) \ /**/ #if BOOST_PP_VARIADICS_MSVC #define BOOST_AUTO_DATA_TEST_CASE( ... ) \ BOOST_PP_CAT( \ BOOST_PP_IIF(BOOST_PP_EQUAL(BOOST_PP_VARIADIC_SIZE(__VA_ARGS__),2), \ BOOST_AUTO_DATA_TEST_CASE_NO_PARAMS, \ BOOST_AUTO_DATA_TEST_CASE_WITH_PARAMS) (__VA_ARGS__), ) \ /**/ #else #define BOOST_AUTO_DATA_TEST_CASE( ... ) \ BOOST_PP_IIF(BOOST_PP_EQUAL(BOOST_PP_VARIADIC_SIZE(__VA_ARGS__),2), \ BOOST_AUTO_DATA_TEST_CASE_NO_PARAMS, \ BOOST_AUTO_DATA_TEST_CASE_WITH_PARAMS) (__VA_ARGS__) \ /**/ #endif 

Example of BOOST_DATA_TEST_CASE usage:

#include <boost/range/iterator_range.hpp> #include <boost/filesystem/path.hpp> #include <boost/filesystem/operations.hpp> struct fixure { fixure() : _Mydir(boost::filesystem::temp_directory_path() / boost::filesystem::unique_path("test-%%%%-%%%%-%%%%-%%%%")) { create_directory(_Mydir); } ~fixure() { _TRY_BEGIN remove_all(_Mydir); _CATCH_ALL _CATCH_END } boost::filesystem::path const _Mydir; }; BOOST_FIXTURE_TEST_SUITE(suite, fixure) namespace { std::array<char const *, 4> const _Ourdata = { "A", "B", "C", "D" }; } BOOST_AUTO_DATA_TEST_CASE(test, _Ourdata, _Str) { BOOST_REQUIRE(_Str); BOOST_REQUIRE(is_directory(_Mydir)); auto const _File = _Mydir / _Str; BOOST_TEST_MESSAGE(_File); std::fstream _Stream; _Stream.open(_File.c_str(), std::ios::out); _Stream << _Str; _Stream.close(); BOOST_REQUIRE(is_regular_file(_File)); } BOOST_AUTO_TEST_SUITE_END() 

Output in test_suite mode:

Running 4 test cases... Entering test module "example" Entering test suite "suite" Entering test case "test" "C:\Users\XXX\AppData\Local\Temp\test-4445-a983-8ba6-09ef\A" Failure occurred in a following context: _Str = A; Leaving test case "test"; testing time: 17ms Entering test case "test" "C:\Users\XXX\AppData\Local\Temp\test-d4c4-c5f6-6154-7200\B" Failure occurred in a following context: _Str = B; Leaving test case "test"; testing time: 10ms Entering test case "test" "C:\Users\XXX\AppData\Local\Temp\test-9f96-4f2c-b132-c541\C" Failure occurred in a following context: _Str = C; Leaving test case "test"; testing time: 9ms Entering test case "test" "C:\Users\XXX\AppData\Local\Temp\test-f0cf-962c-aed3-1cf8\D" Failure occurred in a following context: _Str = D; Leaving test case "test"; testing time: 10ms Leaving test suite "suite"; testing time: 61ms Leaving test module "example"; testing time: 76ms *** No errors detected

As of Boost 1.62, you can use BOOST_DATA_TEST_CASE_F for this:

Declares and registers a data-driven test case, using a particular dataset and a fixture.

BOOST_DATA_TEST_CASE_F(my_fixture, test_case_name, dataset, var1, var2..., varN)
